RADIUS ARM { " A " FRAME } CLAMP BOLTS MODIFICATION

Do you have difficulty removing the 4 bolts which hold the front Radius Arm { "A" frame } to the chassis ?

Maybe the following modification I do might make it easier in the future

The problem with the standard design is that it is difficult to get a socket / box key on to the head of the bolt as it is recessed into the bracket .

My method is to change the normal bolts fitted to longer bolts as per photo below.

I normally fit the bolts from the bottom of the rear suspension on a Robin / Rialto to both sides of the Radius arm .

This time I decided to use the bolts from the BOTTOM of the rear suspension only on the DRIVERS SIDE CLAMP and I changed the bolts for the PASSENGER SIDE CLAMP {which is the most difficult to extract due to the radiator and other bits in the way } to bolts from the TOP of the rear suspension .

This has made it even easier to get a spanner on .

This might not work on some models , but give it a go as you can always fit the originals if it does not .

Tighten the nut shown fully up on the bolt .

Place a normal flat washer over the bolt end and insert bolt / nut / washer assembly in from the chassis side of the clamp mounting .

This Modification makes it easy to fit a spanner on to the bolt head .

After tightening all the clamps cover any exposed threads by fitting a length of greased rubber tubing over the nut and cut off leaving about ¼ inch to 3/8 past the end thread and fill rubber pipe to the end with grease .
